Reliable hot runner cleaning for overmolded hot runner distributors

User-friendly pyrolysis system MAXICLEAN also cleans machine parts with complicated geometries

Cleaning of the often very complex hot runner distributors is usually a great challenge for many users of injection molding plants. “With the very long, internal flow channels in particular, manual cleaning proves impossible,” explains Head of Sales Virgilio Perez Guembe, pointing out that even the use of cleaning granules usually yields poor results.

The expert, therefore, recommends thermal cleaning for large hot runner systems: In a single process step that lasts four to eight hours, MAXICLEAN completely removes all polymer residues without impacting the tools mechanically or thermally, Perez Guembe confirms. “The precisely controllable cleaning process takes place in an external gas-heated cleaning chamber with special hot air routing for optimal distribution of the temperature. The automatic process control monitors the development of low temperature carbonization gases and ensures short cleaning times. Inorganic residues are removed using an appropriate posttreatment method.”

The pyrolysis system MAXICLEAN works without waste water and has a separate afterburner, which completely burns the carbonization gases above 800 °C and discharges them via the chimney. The plant from SCHWING comes with a loading trolley, an exhaust chimney and, if desired, a hydrolysis unit for cleaning the filter.
